As discussed at the following link, the sample listbox, if set to multiple
selection style, cannot be deselected with SetSelection(wxNOT_FOUND), as
stated in the documentation. This occurs purely under windows 7 and is
fine under OSX and under GTK. This can be worked around with
SetSelection(-1,false), however.

Comment:

(In [66243]) Deselect all items in wxMSW wxListBox when selection is set
to -1.

Even though this behaviour is somewhat counterintuitive, the documentation
mentions that this is what should happen and wxGTK and wxOSX already
behave
like this so bring wxMSW in line.

wxListBox::DeselectAll() should probably just call
SetSelection(wxNOT_FOUND)
when the item to leave selected is not specified too now.
